TESTS or CEMENT MADE BY THE STATE EE'GmEER 



DUEINa 1897-1900 



BY EDWIN O. ECKEL O.E. 



I am indebted to Mr Edward A. Bond, state engineer, and 

 Mr William Pierson Judson, deputy state engineer, for permis- 

 sion to nse tlie data on cement tests, liere briefly discussed. Mr 

 Russell S. Greenman bas kindly aided me in many ways. My 

 tbanks are also due to Mr Josepb Morje, of tbe ISTew York state 

 museum, for aid in tbe preparation of botb manuscript and proof. 



Tbe series of cement tests tabulated and discussed were made 

 during 1897, 1898, 1899 and 1900, in tbe cement testing labora- 

 tory of tbe state engineer's oifice, Albany ]^. Y. Tbey are of 

 value as tbey represent tests on various brands made during a 

 comparatively long period in one laboratory. Tbe sequence of 

 tbe tests was interrupted only by one cbange of operators, and 

 by one cbange of testing macbine, botb of wbicb occurred during 

 1900. Mr Cbarles M. Pepson was in cbarge of tbe cement test- 

 ing work from 1897 to July 1, 1900, wben be was succeeded by 

 Mr Pussell S. Greenman, wbo is in cbarge at tbe present date. 



As tbe cement samples were taken from barrels submitted for 

 use, tbe results are of interest as sbowing tbe average quality 

 of tbe various brands as sbipped for use on actual work. Tbe 

 cements tested were, in general, tbose submitted for use on tbe 

 canal improvements. A circular issued in 1899 by Mr Edward A. 

 Bond, state engineer, offered tbe use of tbis laboratory for tbe 

 testing of cements sent in by town and county officials, and some 

 of tbe cement tested during 1900 came in under tbis offer. A 

 number of samples bave also been tested in tbis laboratory for 

 Mr George L. Heins, state arcbitect.
